Hi All,
As you may recall, we have a 14 week old wheaten terrier pup who was on Burns Minibites, but was always hungry and never seemed to gain weight. His poo was also a bit sloppy, but not badly so.
In the end we decided to try him on Arden Grange, and started introducing the Puppy food gradually over 10 days, increasing the Arden Grange in the mix by 10% each day (10%, then 20% etc etc).
Everything went absolutely fine at first. His poo firmed up and he started to gain weight. Then, on the very first day that he had 100% Arden Grange, he started with diarhoea. He doesn't go any more often than before, but the poo itself is totally liquid. He is also flat refusing to eat any dried food. It is now the third day and the poo is still watery. He nibbles his food when he is starving, but with no gusto.
On himself, he is fine enough. Still plays. Bit quieter than normal, but not much. He is very happy to chew on a puppy teething chew, so he doesn't have toothache. Also, I tried giving him some chicken (as a training treat from my hand in return for sits and downs, so it isn't associated with his normal food) and he gobbles it up, so I don't think he isn't hungry.
I'm not sure what to do. Part of me wants to take him to the vet, but on the other hand I keep thinking that as soon as I say we have just changed his food, the vet will say that it is probably that and tell me to wait. My question is, is this common after changing food, and are these symptoms typical? Also, should I just persevere and let him go hungry if he won't eat the Arden Grange? How long would it normally take for his tummy to adapt to the new food, or else how long do I wait before I decide that this food is bad for him?
I feel really guilty as he loved his old food, even if he wasn't gaining weight. Of course, this might all be connected with something completely different and nothing to do with the AG at all.
